    Les coĂ»ts onĂ©reux du traitement dans la drĂ©panocytose conduisent, les patients Ă  s’orienter vers la mĂ©decine traditionnelle. Une Ă©tude antĂ©rieure a montrĂ© l’activitĂ© antifalcimiante de l’extrait aqueux des graines de Cajanus cajan (FabacĂ©es). En vue d’identifier l’extrait le plus actif, il a Ă©tĂ© proposĂ© comme objectif d’évaluer in vitro l’effet antifalcimiant de diffĂ©rents extraits des graines de Cajanus cajan. L’étude de l’activitĂ© antifalcimiante s’est faite sur les prĂ©lĂšvements sanguins de 32 drĂ©panocytaires homozygotes SSFA2. AprĂšs induction de la falciformation des globules rouges, l’ajout d’un extrait dans chaque tube a permis d’évaluer l’activitĂ© antifalcimiante par le dĂ©compte des drĂ©panocytes au microscope optique. Les extraits des graines de Cajanus cajan contiennent des stĂ©rols, polyterpĂšnes, polyphĂ©nols, des flavonoĂŻdes et des alcaloĂŻdes. Tous les extraits diminuaient le taux de drĂ©panocytes d’environ 60% aprĂšs 30 mn de contact. Cette Ă©tude a permis de montrer que les diffĂ©rents extraits des graines de Cajanus cajan possĂšdent des vertus antifalcimiantes tout comme l’extrait aqueux.Mots clĂ©s: Cajanus cajan, extraits, activitĂ© antifalcimiante, AbidjanEnglish Title: Evaluation of the antisickling activity of different extracts of Cajanus cajan (Fabacees) seeds on sickle cells in Abidjan-Cote d’IvoireEnglish AbstractThe expensive costs of treatment in sickle cell disease lead patients to move towards traditional medicine. A previous study showed the antifalcimiant activity of the aqueous extract of the seeds of Cajanus cajan (Fabaceae). In order to identify the most active extract, it has been proposed to evaluate in vitro the antifalcimiant effect of different extracts of Cajanus cajan seeds. The study of antifalcimiante activity was done on the blood samples of 32 SSFA2 homozygous sickle cell patients. After induction of sickling of the red blood cells, the addition of an extract in each tube made it possible to evaluate the antifalcimiant activity by the counting of the sickle cells under an optical microscope. The extracts of Cajanus cajan seeds contain sterols, polyterpenes, polyphenols, flavonoids and alkaloids. All extracts decreased the sickle cell count by about 60% after 30 minutes of contact. This study has shown that the different extracts of the seeds of Cajanus cajan possess antifalcimiante virtues just like the aqueous extract.Keywords:  Cajanus cajan, extracts, antifalcimiant activity, Abidja
